WebOct 29, 2024 · Abstract: Based on the finding that the gain of heat flow inside a power semiconductor device behaves as a low-pass filter (LPF) under the frequency domain, an advanced thermal model developed in the frequency domain has been proposed in recent years. The main advantage of this model is that it can analyze the multitime scale … WebNov 22, 2013 · Once you have designed your filter you can apply it using the function filter or filtfilt. As an example, a simple way to go about this would be: [b,a] = butter (n, Wc) % low pass Butterworth filter with cutoff pi*Wc radians - choose the order of the filter n and cut-off frequency Wc to suit filtered_data = filter (b,a,original_data); Share.
